What is the IP protection level for tunnel lights?
LED tunnel light, the protection grade is divided into dustproof and waterproof. For example, BYD GL-03 IP65, the IP logo, International refers to Protection, IP protection class is composed of two digits, the first digit indicates the lamp dust level to prevent intrusion of foreign objects, second numbers represent the tightness of moisture intrusion and waterproof lamps. The larger the number, the higher the protection level.First number: the dividing range is 0-6 and 6 is the highest level, which means that dust can be completely prevented from invading.Second numbers: the division is 0-8, 8 is the highest grade, the protection against flooding, and can be immersed in water for a long time, the specific time is not clear.
As an instrument used in explosive hazardous areas, the protection level of its enclosure should also be specified and given a certain amount of code, that is, the IP grade number.The shell protection class specified by IEC144 is expressed by a code corresponding to its impact against external objects, puncture ability and water resistance. For example: this type of instrument measuring circuit board should not remove the shell, otherwise it will violate the minimum requirements proposed by IP40. The protection level is made up of two digits, with the word "IP" in front of it.
IPxx dust and water rating - dust rating (first X) - waterproof level (second X)dustproof0: there is no protection1: to prevent large solid invasion2: prevent medium size solid intrusion3: prevent small solids from entering the invasion4: prevent objects larger than 1mm solid access5: to prevent harmful dust accumulation6: completely prevent dust entering
